MECHANICAL DEMONSTRATING DEVICE.

Application filed July 30, 1923. Serial No. 654,791.

This invention relates to devices for demonstrating and testing the flexibility, durability, advantages of construction, and design of wearing apparel for the hands and feet.

One of the objects of the present invention resides in providing a device which will duplicate as nearly as possible in a simple manner, the usual movements of the digits in such a manner that their action on and relation to the wearing apparel may be made manifest.

A further object of this invention resides in providing a compact device for accomplishing this function which is constructed so that it can readily be associated or positioned in exhibiting relation to the desired wearing apparel.

These and other objects will bemanifest.

from a perusal of the following specification when taken in connection with the ac companying drawings, wherein I V Figure 1 is an illustration of the device inserted in the shoe, the toe of the shoe being detached and lifted up to expose the digit members;

Fig. 2 is an enlarged perspective view of the device;

Fig. 3 is a smaller side view;

Fig. 4 is a detail view of the universal mounting of the main toe digit, and

Figures 5 and 6 are perspective views of the small and large digits showing the cam groove.

Referring more particularly to the accompanying drawings, the device comprises a support 1 of any desired shape and preferably of convenient size so that the device as a whole can be inserted either in the shoe, moccasin, boot, slipper, sandal or footwear of any description, or can be inserted in hosiery, gloves, mittens or anything of the like character.

In the front portion of the support 1' are mounted a set of digits shaped to simulate human digits, in the present embodiment,

those of the human foot, and includes live digit membersaltogether. In the construction illustrated, the three intermediate digits 11, 12 and 13 are mounted on the support to move in a, vertical plane, that is, they are' raised and lowered, and to this end, there is provided the upright supports 16 and 17 and the cross pivotal pin 15. Each of these intermediate digits 11, 12 and 13 are perforated to receive the pivotal pin. The out-.

ermost digits, that is, 10 and 14 are universally mounted. In other words, they move not only in a vertical plane butalso in a horizontal plane to simulate a sort of wriggling motion. A simple type of universal mounting for one of these digits is illustrated in Fig. 4, wherein the large digit 14 is shown as hollow at the broken awayportion. This digit is supported by a vertical post 18 carried upright from the support 1. There is pivoted at. its top as at 19, a yoke 20, having a cross bar on which is pivoted as.

at 21, a rod 22 journaled as at 23 in the opposite walls of the digit 14. By means of this mounting, the digit 14 may move in any direction.

Motion is imparted to the respective digits by means of a simple form of mechanism comprising a roller 24provided around its periphery at spaced intervals with a series of pins or striking lugs 25,. These pins as they are rotated around by the roller, strike the rearmost faces 26 to 30, inclusive of the digits thereby lifting the digits in a vertical plane about their pivotal points.

In the case of the outer digits 10 and 14, the striking faces are provided with tortuous channels, so that the pin as it strikes the surface and falls into this channel, will give the digit a lateral or wriggly motion. Motion is imparted to the roller in any desired manner, as by means of a belt 31 running to a pulley 32 driven by a spring motor 33 mounted on a suitable casing 34 carried by the support. It is obvious that any desired type of motive'power or driving mechanism may be used and that other means may be availed of for moving the digits. So also, it is manifest that these digits may be made of any desired materials, such as metals, wood, glass, cork or paper. In this applica tion, the device may be exhibited in windows for the purpose of showing the normal arrangement of toe movement in connection with hygienic shoes or the like, or may be used as a means for testing the durability and Wearing qualities of textile fabric wearing apparel, such as gloves, mittens, hosiery and the like; When used as a testing device the apparatus is especially adaptable as a means for testing the durability of gloves and hosiery, due to the fact that it so closely imitates the actual movements of the human digits.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is I 1. A mechanical demonstrating device comprising a support a digit movably mounted thereon and constructed and arranged to simulate a human digit, and means to impart a wriggling 'movement to said digit.

2. A mechanical demonstrating device comprising a support a digit constructed and arranged thereon to simulate a human digit, and means to impart a substantial universal shifting movement to said digit. 3. A mechanical demonstrating device comprising a support, a digitsimulating a human digit mounted on said support, and means to raise and lower said digit and to simultaneously impart a lateral motion thereto. 1 V p 4;. A mechanical demonstrating device comprising a support, a plurality of related digits movably mounted on said support and arranged to simulate a human digital member, and means to periodically shift said digits including means to impart a wriggling motion to at least one of said digits.

5. A device of the class described comprising a plurality of related digits simulating a human digital member and means to raise and lower said digits and to impart a simultaneous lateral movement to one or more of said digits. 7

6. A device for demonstrating the qualities of wearing apparel for a human digital member comprising a support adapted to be inserted in the article of wearing apparel, a set of digits mounted thereon, means for shifting one or more of said digits to simulate the movement of the digits of the said member.

7. A device for demonstrating the qualie ties of wearing apparel for a human digital.

member comprising a support adapted to be inserted in an article of wearing apparel, a 7

set of digits pivotally mounted on said sup-' port to swing in substantially vertical planes, certain of sand digits being con structed and arranged to move in horizontal planes, and means to positively move said digits. 3 V

8. A device for demonstrating the qualities of wearing apparel for a human digital member comprising a support, a horizontal pivotal bar therein, three digits pivotally mounted on said bar for movement in a substantially vertical plane, a digit on each side of said first digits, a universal'mounting for said last-named digits, and means to ate one of said digits.

9. A. device of the class described comprising a support adapted to be inserted in an article of wearing apparel for the hands or feet, a set of digits on said support, and means to move said digits to cause'the same to simulate the movements of the digits of a digital member.

In testimony whereof. I afiix my signature.
